These are some pictures from my ride in a cycle rickshaw from Bandel to Chinsura in the Hooghly district of West Bengal. Bandel and Chinsura are suburbs of Kolkatta. They are poorer suburbs with a lot of history built around the banks of river Ganga. A commuter rail provides transportation to Kolkatta. The cycle rickshaws and auto-rickshaws provide transportation from the train stations. There are busses but are very unreliable.
The cycle rickshaws are modified roadsters. They are comfortable for two people. Some are modified with facing seats for school children. There are no gears. The rear sprocket seems to be a larger one. The front sprocket looked like a 42-48 teeth.
The slide show has pictures of people in various forms of cycling around. The particular day this picture was taken was the morning of a holiday. Hence the crowd appears to be slim. There are pictures of multiple people on a bike, a cargo trike etc.
A few things to notice: no helmets, no bike lanes, no stop lights and much more. All movement, pedestrian to cars to large trucks happen in a sort of mini critical masses.
